Why is there black stains on my eaves?

Why are there black stains on my eaves?

The black staining that you can see on the eaves is in fact mould. The mould has occurred from water entering the eaves. In the diagram below you can see a detail view of the gutter and eave. You may notice that the gutter is quite a odd design, the gutter is higher on the outside and lower on the inside.

Water can back flow into the eaves, common reasons for this are:

  • Gutters full of debris
  • blocked down pipes
  • gutter fall is inadequate or damaged

Regular maintenance should be carried out on guttering. I recommend an annual clean unless you are a area with lots of trees neighbouring.  While conducting a pre purchase building inspection we are always checking for this or signs of previous back flowing gutters. The eaves can become weak and sagging due to the extra load they carry when moist. We also use moisture meters to ensure the eaves are not carrying any moisture.

This is one of many different defect we look for throughout a pre purchase building inspection.

Have used David for a couple of properties now, wouldn't use anyone else. Incredibly thorough reports and great one on one conversations, explaining everything. Wouldn't buy a house without consulting him! He's helped me dodge a bullet before, that would of cost me a couple of hundred thousand.

Dave was great, very informative, easy to talk too and ensured I seen the issues I needed sorted before putting house on the market. Was worth every dollar as the money spent on my issues I feel will ensure a smooth sale.
Thanks Dave.

I had David do a preventative maintenance inspection on our butcher shop at the Gawler Green. It was a very valuable inspection as we found a leak coming from the tenancy next door. David's thermal imaging and moisture testing was used to find the problem . It was easily fixed before it became a big and expensive repair . His service was professional and great , I'll be using his maintenance inspections regularly.
